What I'm looking for

I'm looking to build maintainable, AI-enabled web products where I can lead frontend and full-stack initiatives, apply LLM and agentic engineering, collaborate with clients, and share knowledge with engineering teams.

At Nisum Technologies, I build large-scale enterprise e-commerce experiences for a leading U.S. retail group using Vue.js, React.js, Next.js, and TypeScript. I lead Micro Frontend architecture, integration, and training while collaborating directly with clients through demos and feedback cycles.

I've expanded my work beyond frontend delivery by building FastAPI services, REST APIs, and AI-enabled applications using OpenAI, Gemini, Hugging Face, LLaMA, Mistral, RAG, LangChain, LlamaIndex, and vector databases. I also use Claude Code, Codex, and structured agent instructions to improve implementation, refactoring, debugging, documentation, and developer workflows.

Previously at Loop Financial Services, I developed fintech modules for payments, user management, lending, invoicing, cash-in-transit, and AI-based email functionality. I led migrations from Create React App to Vite, JavaScript to TypeScript, and GitLab CI/CD to GitHub Actions.

Across consulting, product, and remote teams, I've delivered responsive React interfaces, e-commerce and PWA features, POS and inventory modules, API integrations, and production-quality testing and CI/CD workflows.
